Bridges, skyscrapers, helicopters, and nightlights are all very useful things!
But how did somebody come up with the idea for these things, and how did people figure out how to build them?
In 3-D... More > Engineering: Design and Build Your Own Prototypes, young readers apply science and math skills to tackle real-life engineering problems by figuring out real-life solutions. Using a structured engineering design process, kids learn to brainstorm, build and test a prototype, and redesign. Projects include designing a cardboard chair to understand the stiffness of structural systems and designing and building a set of pan pipes to experiment with pitch and volume in music.
Creating prototypes is a key step in the engineering design process. While many will not work as planned, this is exactly how engineers learn and make improvements to their designs. By trying and retrying, kids learn the value of persistence. 3-D Engineering empowers kids to discover the mechanics of the world we know.< Less
